The unique design, don't worry about the separation of the pen and pen cap. Rotating one end cap, it becomes a pen that can write with smooth writing, and easy to carry. There is a cylinder design in the middle, you can make the gyro twirl on a horizontal surface or on your finger which let you play for smoother and a long time. The led lights makes it more Dazzling. The pen made of high quality metal, good hand feeling, fast rotation, durable, very lightweight and small-size, easy to carry anywhere. Very useful for both students and office staff. Great gift choice for students, office staff, Father's Day, Thanksgiving Day etc. It includes batteries. The logo can be imprinted on it.
